# frozen_string_literal: true
# Shared examples for resource routes.
#
# By default it tests all the default REST actions: index, create, new, edit,
# show, update, and destroy. You can remove actions by customizing the
# `actions` variable.
#
# The subject is expected to be an instance of the controller under test.
#
# It also expects a `base_path` variable to be available which defines the
# base path of the controller, and a `base_params` variable which
# defines the route params the base path maps to.
#
# Examples
#
# # Default behavior
# describe Projects::CommitsController, 'routing' do
# it_behaves_like 'resource routing' do
# let(:base_path) { '/gitlab/gitlabhq/-/commits' }
# let(:base_params) { { namespace_id: 'gitlab', project_id: 'gitlabhq' } }
# end
# end
#
# # Customizing actions
# it_behaves_like 'resource routing' do
# let(:base_path) { '/gitlab/gitlabhq/-/commits' }
#
# # Specify default actions
# let(:actions) { [:index] }
#
# # Add custom actions by passing a hash with action names
# # as keys, and the HTTP method and path as values.
# let(:additional_actions) do
# {
# preview_markdown: [:post, '/:id/preview_markdown'],
# }
# end
# end
